Wind Chill - As If it Wasn't Cold Enough!
On a calm day, our bodies help to insulate us by warming up a thin layer of air close to our skin, known as the "boundary layer". The wind takes this protective layer away, and it takes energy for our bodies to warm up a new layer. As each layer keeps getting blown away, our skin temperature drops, and we feel colder.
Wind also makes you feel colder by evaporating any moisture on your skin. When your skin is wet, it loses heat much faster than when it is dry.
